To all whom it may concern.:

Be it known that I. EARL G. WATBoUs, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new'and useful Im provements in Water-Closets, of which. the following isaspecification.

My invention relates to water closets and consists in a novel combination oi the`ilushing valve with the closet bowl, as well as in a. novel construction-oi the valve itself. v j

In the accompanying drawings, Figure 1 is a vertical section through th'e valve mechanism und its inclosing water chamber; Fig. 2 a perspective view of a water y closet having my invention applied to it; and Fig. 3 a

horizontal section through the 3 3 of Fig. 1.

The same letters o reference are used to indicate p 4corresponding parts in the several views.

valve mechanism for controlling the admission' ofvwater to the closet bowl `tor ushing purposes. The outline or' this valvemechanism is indicated by the dotted lines in Fig. 2, but is shown in enlarged sectional `de vtail in Fig. 1; and as also shown in the latter figure the water chamber 2 is provided at its upper end with an outlet opening 31 which communicates with the rim flush of the closet bowl and at its lower end with an other outlet opening 32 which communicates with the jet thereof.

The valve proper operates within a cylindrical casing 3, into vwhich opens at 5 the upper end of an integrally formed depending water supply pipe 4 whose exteriorly threaderlslower end 6 projects through an opening formed for itin the bottom of the chamber 2. The pipe 4 is flanged above the b ottom wall of the chamber and a packing ring is interposed between said flange and bottom wall.; A nut 7 screwed upon the depending lower end of the pipe 4 serves to clamp the parts tightly together, and also provides a coupling for the connection of the upper end of the main water supply pipe 8, in which latter there is in the-present instance shown a stop cock 9 for permanently cutting off the water supply when desired. l

The upper end of the valve casing 3 is closed by a screw cap 12 and its interior formsa piston chamber in which travels a piston 14 having an integrally formed depending stem l5 carrying the valve 16. This valve 16 is composed in the present instance of a flanged disk formed integral with the valve stern 15 and having seated in it a ring 16 oi suitable flexible material adapted to seat, when the valve is closed, upon an annular valve seat 17 formed upon the inn er wall of the valve casing 3. The ring 16 is held in place within the anged valve casing on. the line disk by means of a cylindrical nutV 18 rscrewed upon the threaded lower end ofthe valve stem l5. 'Thi nut l' is turned to the several externaldiameters indicated, to form the cylindrical portions-18a and 18b at i extreme upperand lower ends; adapted to snugly fit the v,

valve seat 17, and an intermediate reduced portion adapted to permit the free passage of water around it* l;

when the valve is in position for such reduced portion.

to be within the valve seat.

As will be understood from the foregoing, the' valve ply pipe 4 through the valve casing to the interior of the water chamber 2 ,and thence through its discharge openings 31 and 32 to the rim and jet of the closet i bowl. As will also be understood, when the valve is closed the water supply and pressure are entirely c'ut ofi' from' the interior of the chamber 2, so thatfthe latter is wholly relieved from pressure. This is of the utmost importance where the chamber is formed integral-with the earthenware closet bowl,'(and consequently of-the 16 cooperating with the seat 17 controls the passage of water from the inlet' at the upper end of the water supsame material) as .in the present instance, and is of l sufficient size' Ato hold any considerable quantity of water, since under such circumstances if the interior ofthe chamber were in open communication with the-water supply when the valve is closed the pressure within'l it would tend to develop leakages and miglnt` in'some cases be high enoughto burst the chamber.

The pist-on' 14 is oflarger diameter 'than the valve'lld,

so that the water pressure normally admitted from the water supplypipe 4 to the interior ofthe valve casing l 3, between the valve'and piston, would lift the latter and open the valve but for the fact that provision is made for permitting the water to pass to the upper side ofthe piston and prevent such upward 1novement.

This provision consists in the present instance of a hole formed in'the piston and containing a screw,l9" provided with a tapered slot 19 permitting restricted Vpressure upon the top of the valve 16 to hold the latter securely to its seat. Upon relieving the pressure at the upper side of the piston, however, thepreponderating pressure against its lower side (due to the fact that the piston is larger than the valve) will lift the' piston and open the valve; and I will now describe the `means provided for thus relieving the pressure at the' `upper side of the piston, for the purpdse of permitting the g the pressure against its lowerside to lift it and valve and open the latter.

The upper end oi the water. chamber 2 is closed by a cap 21 provided with an opening through which pro-l jects a tubular entension 20 of the screw cap-12 'which l i closes the upper end of the valvecasing 3. A nut 27 screwed upo'n the threaded upper end of this extension een;

' bular extension 2O extends a valve stem 22 which car ries at its lower endl a valve 23 seating upwardly against a valve seat consisting of a ring of fiexible mateV rial 24 in an annular recess in the under side o 4the screw cap 1,2. At its' upper end the valve stem 22 is provided with a h'ead 25 recessed in its top to receive apush button 26. This head 25 fits and is guided within the extended upper end of the nut 27, within which latter is confined a coiled spring 2,9 whose lower end rests upon a plug screwed in the tubular extension 20 and bearidng at its lower end upon a' ring of packing material surrounding the valve stem 22 therein. lr1`he upward pressure of the spring 29 against the head 25 of the valve stem 22 serves to hold the valve 2 3 normally closed. The tpbular extension 2() o .the screw cap'l2 is provided, just above said cap, with radial passages 28 communicating at their inner ends with the central bore through which thc valve stem 22 passes;l and as. that bore is or' a larger diameter than the valve stem, when the latter is depressedand the valve 23 unscatcd the water pressure within the valve casing 3, above the piston 14, may escape through the passages 28 to the interior of the'water chamber 2. The escape thus provided from the upper end of the valve casing, upon unseating the valve 23 by depressing the push button at the upper end of the valve stern, is sufficiently larger vthan therrestricted passage 19L through the piston to at once relieve the pressure above the piston, wherelupon the pressure against its under side will promptly lift the piston and open the main valve 16 to admit the full water supply to the interior of the water chamber further escape of water from the .chamber above the piston, whereupon the continued admission oi water to the chamber labove the piston through the restricted passage 19L in the latter will gradually restore 'the pressure at the vupper side of the piston and countorlmlance the upward pressure upon its under side, and permit the downward pressure upon the top olv the valve 'i6 to restore the parts to normal position and close said valve.

When the piston 14 andthe valve' 16 are in their uppermost position th`e valve seat is closed by thc enlarged. cylindrical portion or flange 18 upon the lower end of the nut 18 carried by the valve stem, so I valve will remain closed (by theange 18h) until the "ppsh button is released and the relief valve permitted' to seat itself, whereupon the 'piston and main valve will begin to descend and the main valve be again opened. As the main valve approaches its seat, the cylindrical portion oi the fiange 18 at the upper end oi the nut 18 will enter the valve seat and gradually cut off the iiow of water through it prior to the final seating of the main valve.

During the time the main valve is. open the 'water passing through it under pressure from the supply pipe 4 will enter the interior of the water chamber 2 more rapidly than it will escape to the closet bowl through the outlet passages 3l and 32 from said chamber, with the result that the chamber will become filled with water. When the main valve yis then closed and the Water supply cut ofi from the water chamber, the water remaining in the latter will escape through the passage 32 at its lower end to the closet bowl and serve to re-fill the latter.

Inorder to prevent water hammer, which is liable to occur at the. moment that the supplemental valve 18b closes the passage or communication through the slow closing valve mechanism', I provide suitable means for trapping water in the space or chamber 13 above-the piston. In the present instance such meanscomprise a tubular extension 14, which coperates with a cir cular recess or socket l2L formed in the casing cap 12 'adjacent the outlet or relief opening which is governed hy the manually operated valve22. The construction and arrangement are such that immediately prior to the closing oi the supplemental valve 18b after a partial inovement ortraverse of the piston 14 the tubular extension 14 thereof will enterthe socket 12, with the result that although the valve 22 may be open the relief orexhaust from the, chamber 13 is closed by the tubular extension and independently of such relief valve. In this manner some of the water is trapped or confined in the space 13 above the piston and such water is utilized as a cushion to prevent water hammer due to any sudden closing of the passage through the casing of the valve mechanism.
